' Renewed December 1, 1938 6 Claims.

This invention relates to broad tape illuminators in general.

Among the objects of the present invention, it is aimed to provide animproved broad tape i1- luminator whereby the tape is advanced acrossthe light aperture of a casing as the same is supplied by a ticker orthe like and the tape wound up in back of the casing by a surface feeddevice to maintain the advancing movement substantially constant as therewind reel increases in diameter.

It is still another object of the present invention to provide animproved broad tape illuminator whereby a tape is advanced across thelight aperture of a casing and then over a the top of the casing intosurface feed engagement with a tape pulling or tape advancing device.

These and other features, capabilities and advantages of the inventionwill appear from the subjoined detail description of specificembodimerits thereof illustrated in the accompanying drawings in whichFigure l is a perspective of a broad tape illuminator associated with acabinet containing a broad tape printer;

Fig. 2 is an enlarged front elevation of the illuminator with theprinter cabinet removed;

Fig. 3 is a section on the line 3-3 of Fig. 2;

Fig. 4 is a section on the line 4-4 of Fig, 3; and

Fig. 5 is an end elevation of another form of illuminator in which thereis used an endless tape having characters or printed matter thereon.

In the embodiment shown, in Figs 1 to 4, there is provided a cabinet Ifor housing a broad tape ticker such as a Dow Jones ticker or the likefrom which the tape is fed upwardly through the slot 2 to theilluminator 3 constituting the main part of the present invention.

The illuminator 3 consists essentially of a rectangular casing 4 havinga base 5, a front wall 6 with an opening or window therein preferablyprovided with a frame 1 for the light transmitting sheet 8 composed ofglass or the like. The casing 4 also preferably has a top wall 9, sidewalls It] and it and a rear wall !2 consisting of a sheet of metal whichextends down as at 13 to be secured to the rear wall E4 of the cabinetI. The side walls is and H preferably have openings [5 at the top andopenings It at the bottom equipped with suitable louvers to provide forthe entrance and exit of air in the interest of ventilation but at thesame time obstructing the passage of light rays from the casing 4.

These side walls It and Il furthermore extend above the wall 9 and areperforated to provide supports for the idlers I! and 18 extending thefull length of the casing '4 and formed at the front and rear ends ofthe casing 4 to form guides for the tape [9 as it crosses the top of thecasing 4. After the tape leaves the ticker, not shown, 5 which isintended to be housed in the cabinet I and passes through the opening 2,it passes under the idler 2i rotatably mounted in the arms 2| and 22secured to the side walls ID and II of the casing 4 and projectingforwardly of the wall 6 10 below the glass plate 8. The tape i9 thenpasses across the glass plate 8 or rather across the window providedwith the glass plate 8, in the present instance, and then over theidlers i8 and I1 down to and onto the reel 23. The reel 23 is preferably15 weighted so that it may properly engage the drive roller 24 to effectsurface feed of the reel 23,

The reel 23 is mounted on the shaft 25 which is slidably mounted in'theguideways formed by the pairs of vertically extending strips 26 and 2120 secured to the rearwardly extendings wings 28 and 29 formed on therear wall 12.

The drive roller 24 in the present instance is provided with a stubshaft 30 journalled in an orifice formed in the Wing 29 while the roller25 24 itself extends through the other wing 28 and is provided withanother stub shaft 31 which is drivingly connected to the electric motor32 connected to the outer side of the wing 28 by the bracket 33,

The casing 4 is preferably provided with any suitable source of light inthe present instance, the upper wall 9 being provided with threedownwardly extending sockets 34, 35 and 36 to receive the elongatedtubular lamps 31, 38 and 39 re- 35 spectively extending at least thefull length of the Window provided with the glass plate 8, see Fig. 4,and substantially the full width of this window, see Fig. 2.

In the embodiment shown in Fig. 5, it is shown 4 how an endless tape 40may be used with this same equipment. Here the endless tape 40 passesinto the cabinet 4| through the opening 42 at the bottom thereof andthen out again through the opening 43 at the top thereof from which 45it passes up under the idler mounted in the brackets 44 disposed at thebottom of the casing 45 and then up across the front of the windowformed in the front of the casing 45 and then over the top and to theback of the casing 45 50 under the weighted roller 45 by which it ispressed into surface driving engagement with the drive roller 41drivingly connected to the motor 48 from which it returns to the cabinet4i through the opening 43.

It is obvious that various changes and modifications may be made to thedetails of construction without departing from the general spirit of theinvention as set forth in the appended claims.

I claim:

1. The combination of an illuminator for a broad tape including a casinghaving a window in a vertically extending wall, a source of light withinsaid casing behind said window, guides, for guiding the tape upwardlyacross said window and then over the top of said casing; a weightedrewind reel for receiving the tape, vertically extending guideways forsaidreel behind said casing and at the lower end thereof, and a surfacedriving roller below said reel and in driving engagement with the tapeon said reel, said guideways being open at the top to facilitate removalof said reel to wind up the tape on said reel.

2. The combination of an illuminator for a broad tape including a casinghaving a window in a vertically extending wall, a source of light withinsaid casing behind said window, tape advancing means mounted behind saidcasing and clear of said source of light, and guides at the bottom ofsaid window and on the top of said casing to guide the tape across saidwindow and then over said casing to said advancing means.

3. The combination of an illuminator for a broad tape including a casinghaving a window in a vertically extending front wall, a top wall, lampsextending down from said top wall behind said window, tape advancingmeans mounted behind said casing and below the level of said lamps, andguides at the bottom of said window and on the top of said casing toguide the tape across said Window and then over said casing to saidadvancing means.

4. The combination of an illuminator for a broad tape including a casinghaving a window in a vertically extending front wall, a top wall,- lampsextending down from said top wall behind said window, a rear wall havinga downward extension and rearwardly extending wings, the downwardextension serving as a support for connecting the casing to a tickercabinet, advancing means supported by said wings and clear of saidlamps, and guides connected to said casing for guiding the tape acrosssaid window and then over said casing to said advancing means.

5. The combination of a ticker cabinet having a tape discharge openingin the top wall thereof, a casing connected to said cabinet and having awindow in a vertically extending wall in sub stantial alinement withsaid opening, a source of light within said casing and behind saidwindow, a rear wall having a downward extension and rearwardly extendingwings, the downward extension serving as a support for connecting thecasing to said ticker cabinet, tape advancing means supported by saidwings and clear of said lamps, and guides for guiding the tape upwardlyfrom said opening across said window and then over said casing to saidadvancing means.

6. The combination of an illuminator for a broad tape including a casinghaving a vertically ext-ending front partition having a window therein,a source of light behind said window within said casing, a weightedroll, wings extending rearwardly from said casing, a continuously drivendrive roll operatively mounted on said wings and below said weightedroll, vertically extending guideways on the inner opposing faces of saidwings for receiving said weighted roll and enabling it to press the tapeinto surface feeding engagement with said drive roll, said guidewaysbeing open at the top to facilitate removal of said roll.
